UIKit SDK 3.0 error

Question

Hi I am using iphone_sdk_3.0_beta_5__9m2735 SDK. When I try to compile my code using simulator 3.0 option I get following error. The code compiles for rest all simulator option ie 2.0, 2.1, 2.2, 2.2.1 While compiling my code I get following error

from /Users/videomac/manish/EXPLab/2009-05-27-11-20 myApp_LL_2/myApp_Prefix.pch:7:
In file included from /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIKit.h:30,

/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/UIKit.framework/Headers/UILocalizedIndexedCollation.h:21: fatal error: method definition not in @implementation context

The errors are located in file UILocalizedIndexedCollation.h which is SDK file.I am using UIKit Framework of SDK 3.0. Can anyone tell me what should I do to remove this error?

Answer 1

Firstly you should discuss beta products here.

However, this is not connected with the beta. You have an error in one of your own header filesprobably a missing '@end' statment.

BTW, google could have solved this for you rather than asking here.

I've traced this problem to be the compiler version being used. From what I can tell, [REDACTED] requires GCC 4.2 while iPhone SDK 2.x only works with GCC 4.0.

Here's a way to fix this.

In your Target Info, select Build separator and look for the section Compiler Version. Then:

1. Select the C/C++ Compiler Version row
2. Set the default to GCC 4.0
3. At the bottom-left control, hit Add Build Setting Condition
4. On the left, choose Device - iPhone OS 3.0
5. On the right, chose GCC 4.2
6. Repeat steps 3 to 5, now with Simulator - iPhone OS 3.0 on step 4.

Apple’s engineer had confirmed that they had a bug in UIKit framework:

We do have a simple workaround for this UIKit bug. In UILocalizedIndexedCollation.h change this:

UIKIT_EXTERN @interface UILocalizedIndexedCollation : NSObject
to
UIKIT_EXTERN_CLASS @interface UILocalizedIndexedCollation : NSObject
